Hi r/selfhosted community,
I've been working on a self-hosted e-mail organizer as a hobby project for some time and I would like to share it with you. This post is self-promotion, and the service itself is free (both gratis and libre). It has been running on my home lab for months now and I hope that some of you will give it a try and find it useful.
It's called Plauna, and you can find the source code here and the Docker image for it here. Plauna helps you organize your e-mails according to the categorizes you define. I started working on this project after moving away from Gmail. I like how Gmail labeled my e-mails automatically but I didn't want to Google read my e-mails. Also, the Gmail labels did not 100% fit my needs. I wanted to have something more flexible.
It works like this: You create the categories you want, and Plauna creates the corresponding folders on your e-mail servers. You categorize the first few e-mails manually, then train the models on your data. Everything happens and stays on your machine. Afterwards, the incoming e-mails are categorized and moved to their respective folders. You can correct any miscategorized e-mails and re-train the models, so Plauna gets more precise the more you use it. You can also use it to connect to more than one e-mail server if you have multiple personal e-mail accounts, like I do.
Plauna is still under heavy development. The service itself is usable but it still needs a lot of polish (especially the UI). I am happy to answer your questions and support you set it up if you need any help. I'm also interested in hearing your feedback.
